Aureus

Aureus is a decentralized application (dApp) designed to simplify the creation of Real-World Asset (RWA) tokens. Users can tokenize assets like gold, silver, and other commodities. The app utilizes Chainlink Functions and price feeds to handle transactions seamlessly, ensuring that the value of the token is pegged accurately to real-world assets. Aureus offers a transparent, secure, and efficient way for users to access and trade tokenized assets on the blockchain. The protocol uses sign protocol to attest users transaction for security. Beside minting of the real world assets tokens, Aureus has a feature to bridge each token to different blockchains using chainlink ccip. Each token can be transferred to different chain and the aureus ccip smart contracts can read the message transacted to the network and mint and send the bridged amount of token to the user after verifying the crosschain transaction.

The project uses chainlink functions and price feeds at its core to make a minting of real world assets. The chainlink function can buy and sell tokens on alpaca broker account. so the tokens are directly backed by assets that are stored in broker account. Each token is directly backed by the assets bought on brokerage. The price of the tokens are determined by the chainlink price feed. for example for the price of gold, XAU token is used.

When users mint tokens, the chainlink functions checks the amount of bought tokens on the broker and approver or reject transaction. when user redeems the tokens the chainlink function sells the assets on the broker and buy usd. the send the usd to usdt and send it to the user account.

When users bridge tokens from network A to network B, users send message the is secured and proved that the user burned their token in the network A, then in the network B the chainlink ccip protocol proved the user and sends the amount of the token for the user.

In the frontend Aureus uses next js and sign protocol.
